MATRIX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 474,809, dated May 17, 1892.

Application filed March 4, 18,91.

.To all whom it may concern.'

Be it known that I, GEORGE CALDER, .I r., a resident of LancasterJ in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Matrix-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to` matrix-machines; and the improvements are applicable to a machine for which Patent No. 445,040 was granted to me January 20, 1891 and it more particularly relates, among other things, to devices for actuating valve-operating mechanism, for steadying the type-holder during the action of the hammer for indicating its position, for moving the matrix-supporting cylinder, for regulating the extent of its steps in the direction of the length of the line, and for insuring accurate alignment of impressions thereon; and the invention consists in the constructions hereinafter described and pointed ont.

In the accompanying drawings, Figure 1 is a vertical section on line a: of Fig. 2. Fig 2 is a partial plan. Fig. 3 is a vertical section on line fy y of Fig. l. Fig. 4 is a section on line a e of Fig. 1, showing cock-operating device. Fig. 5 is a partial elevation, the valveoperating levers and other parts being omitted. Fig. 6 is an end elevation of the matrixbed and devices for controlling its movements. Fig. 7 is an end elevation of type-holder. Fig. S is an elevation in an alternative position of a detail also shown in Fig. 2.

Referring to the aforesaid patent for a more detailed description of parts not directly involved in the present improvements, I will lirst describe means for actuating the cocks 15 and 16, that control the admission and exhaustion of the fluid which is used to operate the hammer and the type-holder. l

c a indicate keys and key-bars. c includes those keys designed to operate the hammer and move the type-holder, and a those that simply move the matrix-bed without impressing it.

2 indicates one of a series ot' springs snitably supported at 7 7 and having one end engaged with a stop 3 and the other wlth a keybar. The depression of the power-arm of the Serial No. 383,699. (No model.)

spring-lever 2 by a key-bar puts the spring under tension, which provides for the ascent of the arm and key when the latter is released by the operator slightly in advance of the fall of the pin 3, which in the meantime is held up by the pressure of bar 75, to be described.V

Below these keys is a movable table a, to the under vsideof which are fixed two rods c and c. Rods b and are adapted to pass freely through said table and are operated directly by appropriate keys. They also pass freely through tables B and C, and are rigidly connected by a bar 19", and are supported by the connection of rod h with a lever Z2, which is weighted, as shown, and has a fulcrum at b", suitably supported by a post or floor B.

c denotes a weighted lever pivotally connected to lever b and rigidly fixed to the plug of a cock c in a pipe, which is adapted when the cock is open to supply air or other Huid under pressure to a cylinder 0.

d indicates a piston, and d its rod, which is arranged to be forced by said fluid-pressure down upon a lever 6,that by suitable connections operates the cocks 15 and 16, which admit air and exhaust the same from the harnmer-cylinder 10 and the type-holder-operating cylinder 8.

d indicates a weighted lever fixed to the plug of a cock d which admits compressed air under the piston Cl to lift it from the lever 6.

All the cocks used in the machine are wastecocks and discharge from the cylinders the air which has been used therein. `The depression of rod ZJ by means of a key opens the inlet-port of cock c and the exhaust-port 0f d. Vhen the key and rod arerelieved IOO by means of weighted levers in manner like that already described in connection With the rods l), and said cocks control the operation piston dy, and pisof a similar cylinder 0 bar 75 against a stop.

ton-rod the latter having a cam corresponding in size to letters of less width than those named. These rods also actuate lever 6. The piston-rodd and the two key-bars b and b correspond to the wide letters m and tu, the rod d being provided with a wider cam 4 than the rod d, which cams determine the length of movement of the matrix-bed, as described in the aforesaid patent. The object of this mechanism is to relieve the operator from the labor of actuating the lever G and lifting its load, this work being done by fluid-pressure. The lever 6 is connected and arranged to lift the bar f, which by its connections operates.

vthey will be first opened and the type-holder moved, and before the said cocks 16 are opened said barf is also provided with a lugf", which when the cocks 15 are opened engages a latch g, which is pivoted to tablcAat-g and has one end loosely engaged in a slot in the side of the stop-box 3l. This latch is moved out of the way of the stop or lug f to permit the barf to ascend higher under the influence of the above-described piston-rods acting upon lever 6 to open the cocks 16.

g denotes a spring arranged in a fixed bumper g", placed in the path of the box 3l, which carries the stops 3. This box is made movable, so that a single spring can be applied thereto with the effect of modifying the -blow of the type-holder bar 75 against each stop supported in the said box, which latter is guided by the posts h, secured to the table A. Whenever a stop is struck by bar 75, the box is moved against spring g, and the evil elects of a jarring concussion are avoided.

h is a stud fixed on the side of the box, and h a latch pivoted to a post h. It has an arm h" supported in the path of the head of bar 75 in such manner that the retreat of the bar when the type-holder is lreturned to its normal position engages said arm and disengages the latch from the stud, as indicated in dotted lines in Fig. l. The spring g softens the concussion of the type-holder and stopbox, being compressed by the impact of the The movement of the box against the spring permits the weighted latch h to drop behind the stud h, and the latch prevents the recoil of the box and consequently avoids the effect of the recoilupon the holder. 'lhe springg, compressed by the operation just described, reacts to move the stop-box when latch 7L is released. The latch g, one end of which enters a slot in the stopbox, is turned on its pivot (see Fig. 2) by said movement of the box, and thereby is moved out of the way of lugf", and this permits barf to ascend high enough to open cock 16 to operate the hammer. When a key-bar is released and lever 6 is thereby relieved from the pressure of rod CZ or d, the barf drops to its normal position. The latch g is again moved into the path of the lug f whenever the stop-box is moved by bar 75. The object of th us temporarily arrestin the ascent of the bar f is to delay the operation of the hammer until the danger of recoil is obviated by locking the stop-box, as described.

The piston and piston-rods above described are provided with cams 4 of sizes corresponding to the thickness of different type. Each of these cams whenever the piston descends engages a slide 5, suitably provided with friction-rollers, which slide operates the ratchetwheel 11 through intermediate devices, which ratchet by the medium of gears and other connections moves the rack 13 and matrixbed a suitable distance for each letter, which distance is regulated by the cam 4, as described in my patent aforesaid. The initial distance of said cams from the operatingslides 5 is regulated by a bar 54, which controls the bellzcrank lever 55, by which the location of stop 57 is determined. Said stop is in the path of an arm 38, which is constantly forced against said stop by a weighted arm (55. These arms are rigidly connected and loosely mounted on the shaft G3 by means of a hub 64. The arm 3S determines the position of the pawl 37, which is pivoted to it, and also the position of the slide 5, which is pivotally connected to arm 38, fixed 011 said hub 64. The bar 24 is arranged on the upper table in the path of bar 54 and has recesses under its bottom. By adjusting said bar 24 the height of bar 54 can be varied with the effect to vary the initial distance of the slide 5 from the cam 4, whereby the extent of the movement of the slide and of the connected mechanism and of the matrix-bed is determined.

hm is a key fixed to bar 54.

i is a spring bearing on Hoor B and against a cross-bar z'b. By depressing the key h" the spring will be compressed and bar 54 lowered and the slide 5 moved away from the cam 4, whereby when the latter is forced down its effect upon the said slide and consequently upon the movements of the matrix-bed Will be lessened, said cam having under the case described a greater distance from the slide than ordinarily, and therefore being adapted to engage said slide during only a part of its vertical movement.

fi denotes a cylinder located above floor A at the side of the stop-box 31 and supported to revolve between posts t" and adapted to indicate the position of the type-holder with reference to the hammer.

25 is a gear splined to the type shaft or bar 75, the rotary movement of said shaft and holder to bring any particular line of type into use being produced by the rack 24.

i is a gear that meshes with gear 25. It

ICC

IIO

is fast on the axis of cylinder t', whereby said cylinder is moved circumferentially at the same time as the type-holder.

i" is a guard or cover provided with a slot j, which is so arranged with reference to lines rests upon ribs or tracks Zt" 76', fixed on' floor A parallel to the top of the wheels. The shaft 28, gears Zr, and matrix-bed 71: are moved forward by a rack 13, operated by the keys a a through the medium of ratchet-wheel Al1 and intermediate devices. The gears are fast on shaft` 28, which has a spline connection with its bearings and slides in them as pushed forward by rack 13.

1S indicates a cylinder, and 2O a supply and exhaust port. v

`30 is a branch of a system of pipes containing air or other fluid undei pressure.

Z is a cock having a waste fast open to the outside air during thev forward movement of the piston in cylinder 18 and its rod 28, which moves the gear and bed. Said cock Zis moved to admit air-pressure to the cylinder for the purpose of returning its piston and the matrix-bed after the completion of a line of impressions by the following mechanism: The cock Z has weighted lever Z which is held normally raised by the arm Z, theA latter being normally held by a bar Z", sliding on table B. This bar Z has a lug m in the path of a bar Z supported to slide in bracket-guides m. Said bar Z engages the said lug m until tripped by a lug m on rack 13, taking against a stop m" on said bar Z, with the effect to move the bar Z out of the pathof lug m', whereupon the cock is turned by the weighted lever to admit to the cylinder air under pressure, by which its piston and shaft 28 and the matrix-bed are returned to their initial position and the lever Z restored to its normal position. The cock Z is closed and its waste-port opened by the action of the cam n of the rack 13 near the close of its return movement, which movement is effected by the opening of said cock Z, as above described. The bar Z is moved into engagement with the lug m by lug m striking stop mm on said bar. The open position of the waste-cock Z corresponds to the position of parts shown in full lines in Fig. 4, which corresponds to the position of connected parts shown in Fig. 2. Fig. 8 and the dotted lines in Fig. 4 correspond to the position of cock Z when its inlet-port is open to admit air to the-cylinder to return the piston and matrix and preparatory to forming a new line of impressions.

n is a cylindrical gear journaled inposts supported on floor B, meshing with the gear Zr and normally held by a spring-stop n The gear n is thus prevented from moving circumferentially except when the force of the sprin g is overcome by the intentional turning of t-he gears 7a, preparatory to beginning the impression of a new line on the matrix. The matrix is suitably wound for this purpose by gears k through the mediumof racks Zt', fast on the bottom of the matrix-bed. The obglect of the cylindrical gear is to maintain the alignment of the impressions.

The type holder or carriage is composed of three concentric portions, (shown 1n the present instance as integrah) the inner one having a round opening 0, the central one a smaller similar opening o', and the outer one an angular opening o. The type has'three correspending parts similarly shaped in cross-section. rlhe portion 0" is an angular nntscrewthreaded to tit on the stem p" of the type, and p is a spring. The type-face p of the smaller sizes is placed at one side of the angular part of the type or type-head p, Whereby the capacity of the head is increased, since the whole head can be utilized for providing thereon larger type-faces without alteration of the vertical page-line on the matrix at which the letters begin their Work.
